Ring Pro won’t chime inside anymore

I have had my ring pro for less than a year. A couple of months ago I had an issue and the technician sent me a new transformer that solved the low battery issue. However, I now have another issue. My doorbell chime is no longer going off when someone rings the doorbell. All of settings in the app are enabled and the notifications get sent to my phone. The chime just simply isn’t going off. Any suggestions or solutions??
